ERROR o.s.web.context.ContextLoader - Context initialization failed

I am struck with this error from 2 days. Any help?
ERROR o.s.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'sessionFilter' defined in file [/usr/local/tomcat/webapps/portal/WEB-INF/classes/META-INF/spring/applicationContext-security.xml]: Unsatisfied dependency expressed through constructor argument with index 1 of type [com.xxx.cloud.common.sessionclient.retrievers.SessionRetrievalStrategy]: : Error creating bean with name 'securityConfig': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'xxx/abc/realm_id' is defined: not found in JNDI environment; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityConfig': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'xxx/abc/realm_id' is defined: not found in JNDI environment
Code:
#Resource(mappedName = "xyz/abc/realm_id")
private String assId;
#Bean
public String assId() {
return assId;
}
applicationContext-Security.xml where the bean is defined, but it doesnt pick up
<beans:bean id="xyz/abc/realm_id" class="com.xxxxxxxx.SecurityConfig">
<beans:property name="assId" value="123456789"/>
</beans:bean>
We cannot use tomcat context.xml.

Failed to determine a suitable driver class

when starting the application, see the below error:

the connection with a sql database, you must configure datasource in application.properties
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://..
spring.datasource.username=//..
spring.datasource.password=//..

if you dont need to config the datasource, you can use the exclude . like this:
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
it would not register the DataSource with default configuration, then passed the issue for throw Exception

sometimes if you bean configuration in same package it won't work. Like the properties loading bean need to be in separate package. Not sure this answer will be accepted or not , for me it worked after moving below code into different package.
#Bean
public PlatformTransactionManager oracleTransactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(oracleEntityManager().getObject());
return transactionManager;
}

Alfresco compatibility with Existing Oracle DB

I have installed Enterprise Version of alfresco and trying to use it with existing Oracle DB schema.
For that I have changed properties in alfresco-global.properties file from PostgreSQL to Oracle.
And I am getting authenticate error while login into alfresco admin.

Invalid property 'priority' of bean class [org.quartz.CronTrigger]: Bean property 'priority' is not writable or has an invalid setter method

Error in SpringFramework 3.x with Quartz 2.x.x
deploy failed WAR file in Jboss 5.2.0 environment
the error
ERROR [org.springframework.web.context.ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'artifactBatchTrigger' defined in class path resource [applicationContext-quartz.xml]: Invocation of init method failed; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'priority' of bean class [org.quartz.CronTrigger]: Bean property 'priority' is not writable or has an invalid setter method.
Does the parameter type of the setter match the return type of the getter?
the xml file config spring
....
<bean name="artifactBatchTask"
class="it.infocamere.middleware.mccplus.quartz.ArtifactBatchTask">
<property name="batchService" ref="artifactBatchService" />
</bean>
......
I suppose a conflict libraries quart with spring.
thank you

including hibernate-validator breaks existing hibernate configuration

I am writing a java module in which I have used hibernate validator. The module works fine by itself.
However when it is included as part of a parent project which uses hibernate for standard entity mapping as an ORM, the parent module breaks down by complaining that it is unable to set up the validation factory (and thus fails to setup the session factory).
exception message is "Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to get the default Bean Validation factory"
-Pulkit
EDIT:
hibernate-validator : 4.3.1.Final
hibernate-core : 3.6.5
